Administrators can configure Apple Push Notification Service (APNS) for an iPhone application. You
cannot use APNS on a simulator in a test environment, nor can you use it with iPod touch or iPad.
Provisioning an Application for Apple Push Notification Service
If your internal users do not have an App Store account, use iTunes as an alternative method of provisioning the Sybase-packaged iPhone application. You can also use this method if you are building your own iPhone application.
